Histone H3 methylation plays a critical role in regulating plant responses to abiotic stresses such as drought, salinity, temperature, light, cadmium, and nutrient stress 🧂🌡️☀️💧

Fig. 1 (shortened, full legend in paper): The role of H3K4 methylation in regulating plant responses to abiotic stresses. (A) The H3K4 demethylase JMJ17 negatively regulates dehydration responses by modulating OST1 expression and ABA-mediated stomatal closure. Under non-ABA conditions, WRKY40 recruits JMJ17 to the ABI5 promoter to remove the H3K4me3 mark (Huang et al., 2019; T.J. Wang et al., 2021). Upon ABA perception, WRKY40 dissociates, activating ABI5 expression via HY5, thereby enhancing stress adaptation (T.J. Wang et al., 2021). JMJ27 and JMJ29 positively regulate drought-responsive genes, while the histone methyltransferases ATX1 and SDG708 induce NCED gene expression, enhancing drought tolerance (Chen et al., 2021; Q. Wang et al., 2021; J. Zhang et al., 2023). Conversely, ATX4 and ATX5 negatively regulate drought responses by activating AHG3 expression (Liu et al., 2018). (B) JMJ15 represses WRKY46 and WRKY70 during salt stress via H3K4me3 demethylation.

Iron is essential to plants, and molecular mechanisms controlling iron uptake and concentration are affected by other essential nutrients such as zinc, copper, phosphorus, and nitrogen 🧲 🌿

📝 Wairich et al.

#PlantScience 🧪
Fig. 2 (shortened, full legend in paper): Example of major mechanisms involving the Fe–P interplay in Arabidopsis. In shoots and under Fe deficiency (↓Fe), reactive oxygen species (ROS) accumulate in chloroplasts, suppressing AtbZIP58 expression, reducing photosynthesis-related genes, and causing chlorosis. Fe deficiency also lowers ascorbic acid (AsA) levels by repressing VITAMIN C 4 (AtVTC4) expression. In combined Fe and P deficiency (↓Fe↓P), AtVTC4 is upregulated, boosting AsA production. AsA scavenges ROS in chloroplasts, restoring AtbZIP58 expression, photosynthesis-related gene activity, and chlorophyll accumulation, maintaining photosynthetic activity and a stay-green phenotype. In low P conditions, blue light activates ELONGATED HYPOCOTYL5 (HY5), inducing LOW PHOSPHATE ROOT 1 (LPR1)–PHOSPHATE DEFICIENCY RESPONSE 2 (PDR2) pathways that oxidize Fe2+ to Fe³+, promoting ROS production, callose deposition, and root growth inhibition.

HY5 integrates light and electrical signaling to trigger a jasmonate burst for nematode defense in tomato

HY5 integrates light and electrical signaling to trigger a jasmonate burst for nematode defense in tomato - Nature Communications
Sun et al. reveal that root-knot nematode attack activates a phyB-HY5 cascade that integrates light and GLR3.5-CaM2 signals to boost JA synthesis in tomato, with HY5 moving from leaves to roots to sustain signaling and trigger JA-mediated defense.

Since both GA and HY5 can be transported from shoot to root, this begs the question of how this shoot to root transport is regulated and how GA and HY5 integrate their signalling. Exciting work for the future 😊

It turns out that a large part of the GA response is coming via HY5 (My favourite transcription factor). GA can increase HY5 levels in the lateral root primordium, leading to a reduction in lateral root growth. hy5 mutants, repsond less to very high GA4 addition!
